摘要： 制造企业内部及企业之间应用的集成问题已成为当前制造业信息化的关键。面向中小制造企业信息化，提出并设计实现了基于面向服务体系架构（Service-Oriented Architectures, SOA）的中小制造企业应用集成系统。在该系统中，制造企业内与企业间的应用通过集成系统所提供的各种服务可跨越防火墙而集成在一起，并可通过该系统中企业应用集成（Enterprise Application Integration, EAI）平台以及工作流系统的协调来互相调用，以实现一个完整的业务目标。

Abstract: The integration of intra and inter manufacturing enterprises applications is one of the key problems in manufacturing informatization. Aiming at small and medium-sized manufacturing enterprises, a SOA-based application integration system is proposed and implemented. In the system, intra and inter manufacturing enterprises applications can be integrated together across firewalls by means of services provided by the integration system. The services are invoked each other to achieve a full business goal by the coordination of EAI platform and workflow control functions of the system.
